.SH NAME
mdraw_per_char_extents \- Obtain per character dimension information. 


.SH SYNOPSIS
void
\fBmdraw_per_char_extents\fP (\fBMFrame\fP *
\fIframe\fP, \fBMText\fP *
\fImt\fP, \fBMDrawMetric\fP *
\fIarray_return\fP, \fBMDrawMetric\fP *
\fIoverall_return\fP)


.SH DESCRIPTION
Obtain per character dimension information. 
.PP
The
.ft B
mdraw_per_char_extents()
.ft R
function computes the text dimension of each character in M\-text
.ft B
mt\fP.
.ft R
The faces given as text properties in
.ft B
mt
.ft R
and the default face of frame
.ft B
frame
.ft R
determine the fonts to draw the text. Each successive element in
.ft B
array_return
.ft R
is set to the drawn metrics of successive characters, which is relative to the origin of the drawing, and a rectangle for each character in
.ft B
mt\fP.
.ft R
The number of elements of
.ft B
array_return
.ft R
must be equal to or greater than the number of characters in
.ft B
mt\fP.
.ft R
.PP
If pointer
.ft B
overall_return
.ft R
is not
.ft C
NULL\fP,
.ft R
this function also computes the extents of the overall text and stores the results in the members of the structure pointed to by
.ft B
overall_return\fP.
